To all whom it may concern:

Be it known that we, RAYMOND 0. BEN-- NER and HARRY F. FRENCH, citizens of the United States, residing at Fremont, 1n the county of sandusky and State of Ohio, have invented a certain new and useful-1m rovement in ElectricBatteries, of which t e'following is a full, clear, and exact description. This invention relates to electric batteries. While the improvement is not limited to any particular type, it .is of especial value in connection with copper oxid batterles having an alkaline electrolyte, such as the Lalande type and its modifications. In this type of batterythe positive electrode usually consists of zinc and the negative of p0w-' dered copper oxid which may be inclosed in a perforated container.

In some modifications of this type of cell the negative electrode consists of a block of molded copper oxid, but the electrochemical action is the same in each case.

' The complete battery consists of a jar e011- taining alkaline electrolyte such as sodium or potasslum hydroxid with an appropriate cover from which the two electrodes are sus-- pended.

We have found that the voltage of the previously mentioned cell is materially raised by adding, preferably to the copper oxid'mass, elemental tellurium or solenium. There does not seem to be any specific proportion of this material that need be used, as it has the voltage raising eflect with small amounts as well as with large amounts.

The characteristic is not limited to elemental tellurium and selenium, but is possessed by the soluble tellurids and selenids, as well as by the igreater part of the insoluble compounds 0 selenium and tellurium. There are various ways that the selenium and tellurium material can be added to the Application filed July 31, 1916. Serial 0. 112,257.

cell, one way being to mix the powdered elemental material with the copper oxid. The tellurium and selenium may also be dissolved in solvents and the copper oxid ele-- ment soaked therein.

The copper oxid may be mixed with tellurium or selenium and heated moderately until the tellurium or selenium melt and bind the copper-oxid particles together. this way the copper oxid mass will be held securely together and cannot sift out of the erforated container. This process may also he used to make a solid block of depolarizer Without using a perforated container. f

In case of the selenids and tellurids or other compounds, these may be ground and mixed with the copper oxid or t ey may be dissolved and the copper oxid mass soaked an alkaline electrolyte with a zinc'electrode and a negative elementcontaining a mixture of copper oxid and selenium.

In testimony whereof, we hereunto aflix our signatures.
